Our subsurface sucker rod pumps are crafted to perfection, adhering strictly to the prestigious API 11AX standards. Proudly API monogrammed and ISO 9001 certified, these pumps represent a blend of cutting-edge technology imported from the USA since the 1980s. With a spectacular array of over 40 models and sizes, our pumps cater to a diverse range of needs, boasting diameters from a sleek 28 mm to a robust 108 mm.
Known as the insert rod pump, the Sucker Rod Pump is a shining star among conventional sucker rod pumps. Ingeniously designed to connect directly to the sucker rod, it simplifies well inspection and workover processes without impacting the tubing. This seamless operation makes it an ideal choice for deeper wells, offering significant time savings and cost reductions in pumping tests.
This pump barrel, refined with a suspension structure, enhances the load-bearing capacity and ensures optimal performance deep within the wells, reaching depths of 500 to 1500 meters. Ingeniously designed, the pump boasts features like the gap bridge structure to fend off bending, with the barrel suspended externally, free from pressure. This impeccable design minimizes eccentric wear, prolonging the service life and boosting pump efficiency. The ingenious reduction of eccentric distance ε=0 curtails pump loss, making this pump a perfect match for deep wells requiring extensive tail pipe support.
